电流为63A的分接开关适用于5~8mm的变压器箱盖（单相除外）：

电流为125A的分接开关适用于5~10mm的变压器箱盖；

动触头结构有夹片式及滚动式，夹片式无代号，顾客若要滚动式，请在订货时加以说明。

我们可以根据顾客要求，制造箱盖下加高的分接开关：

顾客若有其它特殊要求，请在订货加以说明。

The current of 63A tap-changer is applicable to 5~8mm transformer cover (except single phase):

The current of 125A tap-changer is applicable to 5~10mm transformer cover.

The moving contact's structure is clamping type or rolling type.The clamping type has no code number.If you need the rolling type,please

illustrate in ordering.

We can manufacture the tap-changer with raised highness beneath the cover in accordance with the customer's requirement.

If you have other specific requirements please detail it in ordering.
